Description
Ground three-neck round-bottom flask with parallel necks, LBG 3.3, centre NS 24/29, long is a laboratory glassware vessel designed for multi-port reaction, distillation and collection work. Manufactured from borosilicate glass 3.3, it combines thermal shock resistance with chemical durability for routine organic and analytical procedures. The flask offers a nominal volume of 0,1 l and is fitted with three necks arranged in parallel, the centre joint specified as NS 24/29 for secure connection to condensers, dropping funnels or stirring assemblies. Ground joint surfaces support tight, interchangeable fittings typical of standard laboratory setups. With a net weight of 0,070 kg, the compact format suits small-scale synthesis, sample preparation and teaching laboratories where space and reagent economy matter. Supplied as a single piece from manufacturer Labbox, this LBG-type round-bottom flask integrates readily into existing ground-joint systems used for reflux, fractionation and receiving applications. Parallel neck geometry keeps side arms aligned for clearer apparatus layouts on stands and heating mantles, supporting reproducible assembly of multi-component glass trains in research and quality-control environments.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask, round bottom with three necks (parallel), LBG 3.3, cent. 24/29, side 19/2
What is this article?
Flask, round bottom with three necks (parallel), LBG 3.3, cent. 24/29, side 19/2 is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labware.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
